No. of bitstreams: 1 Messias Antonio da Silva.pdf: 2977132 bytes, checksum: a15679b5cedd2062e4385683b350d5f3 (MD5) Previous issue date: 2015-08-14 / The constant π will be presented in this work since its origin, in length and area problems particularly the problem of squaring a circle -, to the most recent researches on algorithms used for the calculus of its decimal expansion. Using the exhaustion method we calculate the length and area of a circle of radius r. We demonstrate the irrationality of π . We also generalize the constant for π convex, simple and closed curves. At last we suggest some educational activities related to the concepts in study. / A constante π será apresentada desde a sua origem, nos problemas de medidas de comprimento, área, em particular o problema da quadratura do círculo, até as pesquisas mais recentes sobre os algoritmos usados para o cálculo, de sua expansão decimal. Usando o método da exaustão calculamos o comprimento e a área de um círculo de raio r. Mostramos a irracionalidade de π . Apresentamos uma generalização de π para curvas fechadas, simples e convexas. Finalmente, sugerimos algumas atividades didáticas envolvendo os conceitos estudados.
